' Fatented. Jan. 12, 190.9.

To all whom it may concern:

Be it known that I, WALTER H. PERKINs, a citizen of the United States, residing at Cheshire, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Ball-Cocks for Flushing-Tanks; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the san1e,'and which said drawings constitute part of this specification, and represent, in

Figure 1, a view partly in. elevation and artly in vertical section of a ball-cock for -ushing tanks constructed in accordance with my invention and shown as applied to the bottom of a flushing tank. Fig. 2 a detached view in side elevation ofthe shank. Fig. 3 a corresponding view of the head. Fig. l 2. view of the head in transverse section on the line a-b of 3.

My invention relates to an improvement in ball-cocks for flushing tanks.

Heretoiore ball-cocks for flushing tanks have been made of cast-metal and have on that account been objectionable because of their cost, and because of the imperfections and por'osities characteristic of cast-metalv construction.

The object of this invention is to produce a ball cock superior to such cast-metal ballcocks in point 01" eheapness,'lightness, simplicity, effectiveness and finish.

With these ends in view my invention eon having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I form the shank 2 of the ball-cock from a single iece of wrought-metal tubing formed towar its upper end with an annular horizontal bearing-flange 3 produced by folding a portion of the metal upon itself. The lower end of the shank is formed with exterior threads 1 for the reception of a nut 5 which is brought to a bearing u )on the lower face of the bottom 6 of the tellingtank, whereby the lower face of the flange 3 is brought to a bearing u on the up er face of the said bottom 6 whic ris forms with a circular opening 7 through which is passed downward for the mounting of the cook. The upper end of the shank is formed the shank with exterior screw threads 8 for coaction" with internal screw threads 9 formed within the body 10 of the cook, the said body 10' being also produced from a single piece of wrought-metal tubing. At its'lower end the body is formed with an outwardlyturned bearing-flange 11 which rests upon a washer 12 placed upon the upper face of the bearingflange 3, the flange character by its provision with several faces as shown in big. 4 whereby it i adapted for the application At its-upper end the shank 2 is contracted to form a concentric port 13 surrounded by an annular upwardly extending rib is forming a seat for a washer-like-valve' 15 secured to the lower face of a flange l6'iocated at the lower end of a tubular valve stem 17; having bearing in a concentric opening 18 in the inwardly turned upper end of The stem 17 is connected at its upperend by a screw: 19 with operating-lever 20 made from a'short length of tubing and mounted upon a pivot 21., in upper end of a flat sheet-metal bracket 22 attached by any suitable means, as for instance, by screws 23, 23, to the body 10, the outer end of the lever 20 receiving one end of-the lever 2 carrying the ball-float. The metal portion of the body 10 is knurled or otherwise treated to form a doe annular recess 25 the upper wall of which is pierced to form downwardly opening water ports 26 which on account of their location discharge the water downwardly into the tank instead of outwardly and upwardly.

A ball cock constructed as shown anddescribed entirely of wrought metal is light, simple and cheap, adapted to be finished at a small cost, and being made of wrought instead of cast metal, has none oi the imperfections or porosities which render cast-metal ball-cocks liable to break and to leak.

i. In a ball-cock for flushing tanlns,.the combination with a wrought-metal body formed with an annular recess having dis char e-openings, having an integral annular bearing-flange consisting of a portion of the metal folded upon itself.

2. in a ball-cock for flushing tanks, the combination with a wrought-metal body formed with an annular recess having discharge-openings, of a wrought-metal shank 11 being given a nut-like to it of an ordinary wrench.

the body 19.

of a wrought rnetal shank having, an annular bearing fiange formed by ,folding a portion of the metal upon itself and the said shank having its upper end contracted to. form a water-port and furnished with a rib to form a valve'seat.

4. In abal -cock for flushing tanks, the combination with a wrought-metal shank having an annular bearing-flange consisting of'af ortion of the metal folded upon itself,

' ofa' ody adapted to be applied to the upper specification in the recess the upper wall of which is pierced to form downwardly openin discharge-openings, a valve-stem mounte in the said head, v 'a valve carried by the said stem, an operating-lever connected with the upper end of the va ve stem, and a bracket mounted upon the said head and carrying the said lever.
